AMD doubles up, announces ATI HD Radeon 4850 X2 and 4870 X2

Sure, times might be tough at AMD, but that's not stopping the crew at ATI from gunning for NVIDIA's newest gear -- the company just announced the new HD Radeon 4850 X2 and 4870 X2. Aimed at the "super high-end" of the market, the $399 4850 X2 and $599 4870 X2 feature two GPU chips on a 625 or 750MHz bus, respectively, with up to 2GB of 900MHz GDDR5 RAM. ATI says that there's a 20 percent overhead from pairing up the processors, so the X2s should offer 180 percent of the single GPU cards -- certainly enough to outgun a single NVIDIA GTX 280, and reportedly enough to match a dual-280 setup depending on the game. We'll see for sure when the inevitable flood of benchmarks hits when these bad boys arrive next month -- any gamers out there going to take the plunge?
